The present invention relates to novel carboxamide compounds and their use for the manufacture of a medicament. The carboxamide compounds are inhibitors of calpain (calcium dependant cysteine proteases). The invention therefore also relates to the use of these carboxamide compounds for treating a disorder associated with an elevated calpain activity.

Calpains are intracellular, proteolytic enzymes from the cysteine protease group and are found in many cells. The enzyme calpain is activated by elevated calcium concentration, with a distinction being made between calpain I or μ-calpain, which is activated by μ-molar concentrations of calcium ions, and calpain II or m-calpain, which is activated by m-molar concentrations of calcium ions. Currently, further calpain isoenzymes are also postulated (M. E. Saez et al.; Drug Discovery Today 2006, 11 (19/20), pp. 917-923; K. Suzuki et al., Biol. Chem. Hoppe-Seyler, 1995, 376 (9), pp. 523-9).

Calpains play an important role in various physiological processes. These processes include the cleavage of different regulatory proteins such as protein kinase C, cytoskeletal proteins such as MAP 2 and spectrin, and muscle proteins, protein degradation in rheumatoid arthritis, proteins in the activation of platelets, neuropeptide metabolism, proteins in mitosis, and others which are listed in: M. J. Barrett et al., Life Sci. 1991, 48, pp. 1659-69; K. Wang et al., Trends in Pharmacol. Sci. 1994, 15, pp. 412-419.

Elevated calpain levels have been measured in various pathophysiological processes, for example: ischemias of the heart (e.g. myocardial infarction), the kidney, the lung, the liver or the central nervous system (e.g. stroke), inflammations, muscular dystrophies, cataracts of the eyes, diabetes, HIV disorders, injuries to the central nervous system (e.g. brain trauma), Alzheimer's, Huntington's, Parkinson's diseases, multiple sclerosis etc. (see K. K. Wang, above) and infectious diseases such as malaria (I M Medana et al., Neuropath and Appl. Neurobiol. 2007, 33, pp. 179-192). It is assumed that there is a connection between these diseases and generally or persistently elevated intracellular calcium levels. This results in calcium-dependent processes becoming hyperactivated and no longer being subject to normal physiological control. A corresponding hyperactivation of calpains can also trigger pathophysiological processes.

For this reason, it was postulated that inhibitors of calpain could be of use for treating these diseases. This postulate was confirmed by a variety of investigations. Thus, Seung-Chyul Hong et al., Stroke 1994, 25 (3), pp. 663-669, and R. T. Bartus et al., Neurological Res. 1995, 17, pp. 249-258, have demonstrated that calpain inhibitors have a neuroprotective effect in acute neurodegenerative impairments or ischemias such as occur after cerebral stroke. K. E. Saatman et al., Proc. Natl. Acad. Sci. USA, 1996, 93, pp. 3428-3433 describe that following experimental brain trauma, calpain inhibitors also improved recovery from the memory performance deficits and neuromotor impairments. C. L. Edelstein et al., Proc. Natl. Acad. Sci. USA, 1995, 92, pp. 7662-6, found that calpain inhibitors have a protective effect on hypoxia-damaged kidneys. Yoshida, Ken Ischi et al., Jap. Circ. J. 1995, 59 (1), pp. 40-48, pointed out that calpain inhibitors had favorable effects following cardiac damage which was produced by ischemia or reperfusion. The calpain inhibitor BDA-410 delayed the progression of malaria infection in a mouse model of malaria pathogenesis as shown by X. Li et al., Mol. Biochem. Parasitol. 2007, 155 (1), pp 26-32.

More recent studies have shown in calpastatin transgenic animals that the expression of the natural inhibitor of calpain significantly attenuates the pathophysiological effects of activated calpain in experimental glomerulonephritis shown by J. Peltier et al., J A, Soc Nephrol. 2006, 17, pp. 3415-3423, in cardiovascular remodeling in angiotensin II-induced hypertension, in impaired synaptic transmission in slow-channel congenital myasthenic syndrome shown by Groshong J S et al., J Clin Invest. 2007, 117 (10), pp 2903-2912, in excitotoxic DNA fragmentation via mitochondrial pathways shown by J Takano et al., J Biol Chem. 2005, 280 (16) pp. 16175-16184, and in necrotic processes in dystrophic muscles shown by M J Spencer et al., Hum Mol Gen, 2002, 11(21), pp 2645-2655.

It has been shown in recent years that both the function and the metabolism of a number of important proteins involved in the development of Alzheimer's disease are modulated by calpain. Various external influences such as, for example, excitotoxins, oxidative stress or else the action of amyloid protein lead to hyperactivation of calpain in the nerve cell, causing, as cascade, a dysregulation of the CNS-specific kinase cdk5 and subsequently a hyperphosphorylation of the so-called tau protein. Whereas the actual task of the tau protein consists of stabilizing the microtubules and thus the cytoskeleton, phosphorylated tau is no longer able to fulfill this function; the cytoskeleton collapses, axonal transport of matter is impaired and thus eventually the nerve cell degenerates (G. Patrick et al., Nature 1999, 402, pp. 615-622; E. A. Monaco et al.; Curr. Alzheimer Res. 2004, 1 (1), pp. 33-38). Accumulation of phosphorylated tau additionally leads to the formation of so-called neurofibrillary tangles (NFTs) which, together with the well-known amyloid plaques, represent a pathological hallmark of Alzheimer's disease. Similar changes in the tau protein, generally referred to important feature of as tauopathies are also observed in other (neuro)degenerative disorders such as, for example, following stroke, inflammations of the brain, Parkinsonism, in normal-pressure hydrocephalus and Creutzfeldt-Jakob disease.

The involvement of calpain in neurodegenerative processes has been demonstrated in transgenic mice with the aid of calpastatin, a specific and natural inhibitor of calpains (Higuchi et al.; J. Biol. Chem. 2005, 280 (15), pp. 15229-15237). It was possible with the aid of a calpain inhibitor to reduce markedly the clinical signs of acute autoimmune encephalomyelitis in a mouse model of multiple sclerosis (F. Mokhtarian et al.; J. Neuroimmunology 2006, Vol. 180, pp. 135-146). It has further been shown that calpain inhibitors on the one hand block the Ab-induced degeneration of neurons (Park et al.; J. Neurosci. 2005, 25, pp. 5365-5375), and in addition reduce the release of the β-amyloid precursor protein (β APP) (J. Higaki et al., Neuron, 1995, 14, pp. 651-659). With this background, calpain inhibitors having sufficient CNS availability represent a novel therapeutic principle for the treatment of neurodegenerative disorders in general and in particular also of Alzheimer's disease.

The release of interleukin-1α is likewise inhibited by calpain inhibitors (N. Watanabe et al., Cytokine 1994, 6(6), pp. 597-601). It has additionally been found that calpain inhibitors show cytotoxic effects on tumor cells (E. Shiba et al. 20th Meeting Int. Ass. Breast Cancer Res., Sendai Jp, 1994, 25.-28. Sep., Int. J. Oncol. S(Suppl.), 1994, 381).

The involvement of calpain in HIV disorders has only recently been shown. Thus, it has been demonstrated that the HIV-induced neurotoxicity is mediated by calpain (O'Donnell et al.; J. Neurosci. 2006, 26 (3), pp. 981-990). Calpain involvement in the replication of the HIV virus has also been shown (Teranishi et al.; Biochem. Biophys. Res. Comm 2003, 303 (3), pp. 940-946).

Recent investigations indicate that calpain plays a part in so-called nociception, the perception of pain. Calpain inhibitors showed a distinctly beneficial effect in various preclinically relevant models of pain, e.g. in the thermally induced hyperalgesia in rats (Kunz et al.; Pain 2004, 110, pp. 409-418), in Taxol-induced neuropathy (Wang et al.; Brain 2004, 127, pp. 671-679) and in acute and chronic inflammatory processes (Cuzzocrea et al.; American Journal of Pathology 2000, 157 (6), pp. 2065-2079).

The involvement of calpain in the development of kidney diseases, such as chronic kidney diseases, e.g. diabetic nephropathy, has also been shown recently. Thus, it has been demonstrated by Y. Shi et al. in animal models that the natural calpain inhibitor calpastatin is down regulated during renal ischemia reperfusion (Am. J. Physiol. Renal Physiol. 2000, 279, pp. 509-517). Furthermore, A. Dnyanmote et al., Toxicology and Applied Pharmacology 2006, 215, pp. 146-157, have shown that inhibition of calpain via overexpression of calpastatin reduces the progression of DCVC-induced renal injury in a model of acute renal failure. In addition, Peltier et al. have demonstrated that calpain activation and secretion promotes glomerular injury in experimental glomerulonephritis (J. Am. Soc. Nephrol. 2006, 17, pp. 3415-3423). It has also been shown that calpain inhibitors reduce renal dysfunction and injury caused by renal ischemia-reperfusion and thus may be useful in enhancing the tolerance of the kidney against renal injury associated with aortovascular surgery or renal transplantation (P. Chatterjee et al., Biochem. Pharmacol. 2005, 7, pp. 1121-1131).

Calpain has also been identified as a central mediator essential for parasitic activity. Parasites like Plasmodium falciparum and Toxoplasma gondii exploit host cell calpains to facilitate escape from the intracellular parasitophorous vacuole and/or host plasma membrane Inhibition of calpain-1 in hypotonically lysed and resealed erythrocytes prevented the escape of P. falciparum parasites, which was restored by adding purified calpain-1. Similarly, efficient egress of T. gondii from mammalian fibroblasts was blocked by either small interfering RNA-mediated suppression or genetic deletion of calpain activity and could be restored by genetic complementation (D. Greenbaum et al., Science 324, 794 (2009). Because parasites that fail to escape from their host cells are unable to proliferate, suggesting a strategy for anti-parasitic therapeutics. Pharmacological inhibition of calpain has been shown to exert anti-malarial activity, and hence presents a novel strategy for anti-parasitic strategy such as diseases caused by protest infections like malaria or toxoplasmosis (Li et al., Mol Biochem Parasitol. 2007; 155(1): 26-32; Jung et al. Archives of Pharmacal Research (2009), 32(6), 899-906, Chandramohanadas et al. Science (2009), 324, 794).

Further possible applications of calpain inhibitors are detailed in: M. Pietsch et al. Current Topics in Medicinal Chemistry, 2010, 10, 270-293; M. E. Saez et al.; Drug Discovery Today 2006, 11 (19/20), pp. 917-923; N. O. Carragher, Curr. Pharm. Design 2006, 12, pp. 615-638; K. K. Wang et al.; Drugs of the Future 1998, 23 (7), pp. 741-749; and Trends in Pharmacol. Sci. 1994, 15, pp. 412-419.

With the calpain inhibitors described to date a general distinction is made between irreversible and reversible inhibitors, and peptide and non-peptide inhibitors.

Irreversible inhibitors are usually alkylating substances. They have the disadvantage that they firstly react unselectively and/or are unstable in the body. Thus, corresponding inhibitors often show unwanted side effects such as toxicity, and application thereof is therefore markedly restricted. The irreversible inhibitors include for example epoxides such as E64, α-halo ketones, and disulfides.

A large number of known reversible calpain inhibitors are peptide aldehydes which are derived in particular from di- or tripeptides such as, for example, Z-Val-Phe-H (MDL 28170). Derivatives and prodrugs structurally derived from aldehydes are also described, especially corresponding acetals and hemiacetals (e.g. hydroxytetrahydrofurans, hydroxyoxazolindines, hydroxymorpholines and the like), but also imines or hydrazones. However, under physiological conditions, peptide aldehydes and related compounds usually have the disadvantage that, owing to their reactivity, they are frequently unstable, are rapidly metabolized and are prone to unspecific reactions which may likewise cause toxic effects (J. A. Fehrentz and B. Castro, Synthesis 1983, pp. 676-78).

In recent years, a number of non-peptide carboxamides having a β-keto function in the amine moiety and inhibiting calpain have been described. Thus, WO 98/16512 describes 3-amino-2-oxo carboxylic acid derivatives whose amino group is amidated with a 4-piperidinecarboxylic acid compound. WO 99/17775 describes similar compounds which are amidated with a quinolinecarboxylic acid. WO 98/25883, WO 98/25899 and WO 99/54294 describe 3-amino-2-oxo carboxylic acid derivatives whose amino group is amidated with a substituted benzoic acid. WO 99/61423 describes 3-amino-2-oxo carboxylic acid derivatives whose amino group is amidated with an aromatic carboxylic acid carrying a tetrahydroquinoline/isoquinoline and 2,3-dihydroindole/isoindole residue. Similar compounds in which the aromatic carboxylic acid residue carries a heterocyloalkyl radical or (hetero)aryl radical which is optionally connected via a linker are described in WO 99/54320, WO 99/54310, WO 99/54304 and WO 99/54305. Likewise, WO 08/080969 describes nicotinamides of 3-amino-2-oxo carboxylic acid derivatives that in position 2 of the pyridine ring are linked to a substituted pyrazole via a nitrogen atom. WO 03/080182 describes the use of the aforementioned amides for the treatment of pulmonary diseases. The nonpeptide calpain inhibitors mentioned therein also have a number of disadvantages, in particular a low or absent selectivity in respect of related cysteine proteases, such as various cathepsins, likewise possibly leading to unwanted side effects.

WO 07/016589 and WO 08/106130 describe 2-oxo carboxylic acid derivatives carrying a N-acylated 2-pyrrolidinecarboxylamido group in the 3-position. Also disclosed is their use for treating hepatitis C virus infections.

Carboxamides comprising an α-ketoamide moiety in the amine component, in particular those described in WO 08/080969, have been demonstrated to be highly effective and selective calpain inhibitors. However, as found out by the inventors of the present invention, in some cases they have limited cytosolic stability, namely in humans, possibly resulting in their premature clearance from the cytosol. As a consequence, the pharmacokinetics of these compounds may be insufficient.

The cytosolic degradation of said carboxamide compounds having an α-ketoamide moiety is believed to be mainly caused by metabolic reduction of the carbonyl function in the α-position. Carbonyl reduction is an important step in Phase I metabolism of carbonyl-containing drugs by converting aldehyde, ketone or quinone moieties to alcohols to facilitate the elimination by Phase II conjugation or direct excretion (M. J. C. Rosemond and J. S. Walsh: “Human carbonyl reduction pathways and a strategy for their study in vitro”, Drug Metabolism Reviews, 2004, 36, 335-361). Human carbonyl-reducing activities are ubiquitous, found in many tissues including liver, lung, brain, heart, kidney, and blood. Multiple human carbonyl-reducing enzymes have been characterized, including medium-chain (MDR), and short-chain (SDR) dehydrogenases/reductases, aldo-keto reductases (AKR), and quinone reductases (QR), most of these are present in liver cytosols, except for some SDR family present in liver microsomes and mitochondria as described in F. Hoffmann and E. Maser: “Carbonyl reductases and pluripotent hydroxysteroid dehydrogenases of the shortchain dehydrogenases/reductases superfamily”, Drug Metabolism Reviews 2007, 39, 87-144.

The present invention is thus based on the object of providing compounds which inhibit calpain with high affinity and selectivity. The compounds are further intended to display enhanced cytosolic stability in human cells, such as hepatocytes, and in consequence improved pharmacokinetics.

This object and further objects are achieved by the carboxamide compounds of the general formula I described below, the pharmaceutically suitable salts, the prodrugs, the hydrates and the tautomers thereof:

They are additionally distinguished by a high selectivity in relation to the inhibition of the calpain compared with other cysteine proteases, such as cathepsin B, cathepsin K, cathepsin L and cathepsin S, and by their improved stability against cytosolic degradation.

The carboxamide compounds of the invention of the formula I, their salts, their prodrugs, their hydrates and their tautomers are therefore particularly suitable for treating disorders and conditions in creatures, especially human creatures, which are associated with an elevated calpain activity.

The medicament comprises at least one carboxamide compound of the formula I, as described herein, the tautomer, the hydrate or a prodrug of compound I, or a pharmaceutically suitable salt of compound I or of the tautomer, the hydrate or a prodrug of I.

This carboxamide compound, its salts, prodrugs, hydrates and tautomers like the compounds of formula I effectively inhibit calpain even at low concentrations. They are additionally distinguished by a high selectivity in relation to the inhibition of the calpain compared with other cysteine proteases, such as cathepsin B, cathepsin K, cathepsin L and cathepsin S, and by their improved stability against cytosolic degradation. Therefore, these carboxamide compounds are particularly suitable for treating disorders and conditions in creatures, especially human creatures, which are associated with an elevated calpain activity. The invention therefore also relates to the use of these carboxamide compounds, their tautomers, their hydrates and their pharmaceutically suitable salts for the manufacture of a medicament, in particular of a medicament which is suitable for the treatment of a disorder or a condition which is associated with an elevated calpain activity as described herein for the compounds of formula I. As regards the tautomers, the hydrates, the pharmaceutically suitable salts or the prodrugs reference is made to the compounds of formula I.

The carboxamide compounds of the formula I may be present in the form of the α-ketoamide, as shown in the formula I. Alternatively they may also be present in the form of a hydrate, i.e. the keto group in the α-position relative to the amide moiety in the amine component is transformed into two geminal hydroxy groups, as shown in the formula I-H below. R¹, R², R³, R⁴, R⁵, m and n in formula I-H have the aforementioned meanings.

In the presence of water, especially under physiological conditions, usually both the α-ketoamide form and the hydrate form are present in a mixture.

Where only the α-ketoamide form is indicated in the following formulae and descriptions, it is intended to include also the hydrate and mixtures thereof with the α-ketoamide form unless indicated otherwise. Hydrates and α-ketoamide forms are equally suitable as calpain inhibitors.

The carboxamide compounds of the invention of the formula I are also able to form tautomers which are equally suitable as calpain inhibitors. Particular examples of tautomers to be mentioned are the compounds of the formula I-T:

R¹, R², R³, R⁴, R⁵, m and n in formula I-T have the aforementioned meanings.

The carboxamide compounds of the invention of the formula I can also form hemiacetals, hemiketals, acetals or ketals with alkanols. These compounds are equally suitable as calpain inhibitors as they are prodrugs of the compounds I. Accordingly, compounds where one or both of the geminal hydroxy groups shown in formula I-H are a radical derived from an alkanol, and especially C₁-C₆-alkoxy, can also be used according to the invention.

The term prodrug, as used herein and in the claims refers to a compound which is transformed under metabolic conditions into a compound of the formula I. Apart from the aforementioned hemiacetals, hemiketals, acetals and ketals prodrugs of the compounds I include the compounds of the formula I, wherein the oxygen atom of the keto group in α-position to the amide moiety is replaced with a group O-Alk-O, S-Alk-O or S-Alk-S, where Alk is linear C₂-C₅-alkandiyl, which may be unsubstituted or substituted with 1, 2, 3 or 4 radicals selected from C₁-C₄-alkyl or halogen, examples for such groups including O(CH₂)₂O, O(CH₂)₅O, O(CH₂)₄O, S(CH₂)₂O, S(CH₂)₅O, S(CH₂)₄O, etc. Further prodrugs or the compounds I include the compounds of the formula I, wherein the keto group in α-position to the amide moiety is replaced with a group C═NR⁶, where R⁶ is selected from H, C₁-C₆-alkyl, C₁-C₆-alkoxy, C₂-C₆-alkenyl, C₃-C₆-cycloalkyl, C₃-C₆-cycloalkyl-C₁-C₄-alkyl, C₂-C₆-alkenyloxy, C₃-C₆-cycloalkyloxy, C₃-C₆-cycloalkyl-C₁-C₄-alkyloxy. Under metabolic conditions, the aforementioned prodrugs are transformed into the corresponding α-ketoamide compounds of the formula I or into the corresponding hydrates of formula I-H. Therefore, said prodrugs and their pharmaceutically acceptable salts are also part of the invention.

It is equally possible to use pharmaceutically suitable salts of the carboxamide compounds of the formula I, of their tautomers, their hydrates or of their prodrugs, especially acid addition salts with physiologically tolerated organic or inorganic acids. Examples of suitable physiologically tolerated organic and inorganic acids are hydrochloric acid, hydrobromic acid, phosphoric acid, nitric acid, sulfuric acid, organic sulfonic acids having 1 to 12 carbon atoms, e.g. C₁-C₄-alkylsulfonic acids such as methanesulfonic acid, cycloaliphatic sulfonic acids such as S-(+)-10-camphorsulfonic acids, and aromatic sulfonic acids such as benzenesulfonic acid and toluenesulfonic acid, di- and tricarboxylic acids and hydroxy carboxylic acids having 2 to 10 carbon atoms, such as oxalic acid, malonic acid, maleic acid, fumaric acid, mucic acid, lactic acid, tartaric acid, citric acid, glycolic acid and adipic acid, as well as cis- and trans-cinnamic acid, furan-2-carboxylic acid and benzoic acid. Further suitable acids are described in Fortschritte der Arzneimittelforschung, Volume 10, pages 224 et seq., Birkhäuser Verlag, Basel and Stuttgart, 1966. The physiologically tolerated salts of the compounds of the formula I may be in the form of mono-, di-, tri- or tetrasalts, meaning that they may comprise 1, 2, 3 or 4 of the aforementioned acid molecules per molecule of the formula I. The acid molecules may be present in their acidic form or as anion.

The compounds of the invention may be in the form of a mixture of diastereomers, or of a mixture of diastereomers in which one of the two diastereomers is enriched, or of essentially diastereomerically pure compounds (diastereomeric excess de>90%). The compounds are preferably in the form of essentially diastereomerically pure compounds (diastereomeric excess de>90%). The compounds I of the invention may furthermore be in the form of a mixture of enantiomers (for example as racemate), of a mixture of enantiomers in which one of the two enantiomers is enriched, or essentially in enantiomerically pure compounds (enantiomeric excess ee>90%). However, the compounds of the invention are frequently prone to racemization in relation to the stereochemistry of the carbon atom which carries the radical R¹, so that mixtures are frequently obtained in relation to this carbon atom, or compounds which exhibit a uniform stereochemistry in relation to this C atom form mixtures under physiological conditions. However, in relation to other stereocenters and the occurrence, associated therewith, of enantiomers and diastereomers, it is preferred to employ the compounds enantiomerically pure or diastereomerically pure.

In the context of the present description, unless stated otherwise, the terms “alkyl”, “alkoxy”, “alkylthio”, “haloalkyl”, “haloalkoxy”, “haloalkylthio”, “alkenyl”, “alkynyl”, “alkylene” and radicals derived therefrom always include both unbranched and branched “alkyl”, “alkoxy”, “alkylthio”, “haloalkyl”, “haloalkoxy”, “haloalkylthio”, “alkenyl”, “alkynyl” and “alkylene”, respectively.

The prefix C_(n)-C_(m)-indicates the respective number of carbons in the hydrocarbon unit. Unless indicated otherwise, halogenated substituents preferably have one to five identical or different halogen atoms, especially fluorine atoms or chlorine atoms.

According to a preferred embodiment of the invention the compounds of the formula I are predominantly in the S-configuration at the carbon atom carrying the radical R¹, and according to a particular preferred embodiment the compounds I are completely S-configurated at said position.

According to one aspect of the invention the hydrogen atom linked to the carbon atom carrying the radical R¹ of a compound I is replaced by a deuterium atom, as shown in formula I-D below. R¹, R², R³, R⁴, R⁵, m and n in formula I-H have the aforementioned meanings.

The degree of deuteration at said position usually exceeds 80%, preferably exceeds 90% and in particular exceeds 95%. The deuterated diasteromers of formula I-D often show a markedly higher stability against racematisation than their counterparts of formula I, probably due to a kinetic isotope effect (see F. Maltais et al. J. Med. Chem, DOI 10.1021/jm901023f). Thus, it is generally possible to stabilize the S-configuration at the carbon atom carrying radical R¹ of compounds I according to the aforementioned preferred embodiments of the invention, by introducing a deuterium at that carbon atom.

The compounds of the general formulae I and I-H which are indicated in Tables 1 to 35 below, and their tautomers, prodrugs and pharmaceutically acceptable salts, represent per se preferred embodiments of the present invention. The meanings for R², R³, m and R⁵ indicated in Table A below represent embodiments of the invention which are likewise preferred independently of one another and especially in combination.

The compounds of the invention of the general formula I and the starting materials used to prepare them can be prepared in analogy to known processes of organic chemistry as are described in standard works of organic chemistry, e.g. Houben-Weyl, “Methoden der Organischen Chemie”, Thieme-Verlag, Stuttgart, Jerry March “Advanced Organic Chemistry”, 5^(th) edition, Wiley & Sons and the literature cited therein, and R. Larock, “Comprehensive Organic Transformations”, 2^(nd) edition, Weinheim, 1999 and the literature cited therein. The carboxamide compounds of the invention of the general formula I are advantageously prepared by the methods described below and/or in the experimental section.

The compounds of the formula I can be prepared in analogy to the schemes and methods described in WO 99/54305, pp. 6-10 and in WO 2008/080969, pp. 65-70. An important access to compounds of the formula I is depicted in scheme 1.

In scheme 1, R¹, R², R³, R⁴, R⁵, m and n exhibit the aforementioned meanings.

In a first step i), a carboxylic acid II is converted by reaction with an amino hydroxy amide III into a corresponding hydroxy diamide IV. In this connection, conventional peptide coupling methods are ordinarily used, as are described for example in R. C. Larock, Comprehensive Organic Transformations, VCH Publisher, 1989, pages 972-976, or in Houben-Weyl, Methoden der organischen Chemie, 4^(th) edition, E5, Chap. V. It may be advantageous firstly to activate the carboxylic acid II. For this purpose, for example, the carboxylic acid II is reacted with a coupling agent, e.g. a carbodiimide such as dicyclohexylcarbodiimide (DCC), CDI (carbonyldiimidazole), carbonyldipyrazole, DCI (diisopropylcarbodiimide) or 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) in the presence of hydroxybenzotriazole (HOBt), nitrophenol, pentafluorophenol, 2,4,5-trichlorophenol or N-hydroxysuccinimide, to obtain an activated ester IIa. It may further be advantageous to prepare the activated ester IIa in the presence of a base, for example a tertiary amine. Further suitable coupling agents for step I are those mentioned for step iii) below, sucvh as benzotriazole derivatives, pyridinotriazole derivatives and phosphonium activators.

The activated ester IIa is subsequently reacted with the amino hydroxy amide of the formula III or its hydrohalide salt to give the hydroxy diamide IV. The reaction normally takes place in anhydrous inert solvents such as chlorinated hydrocarbons, e.g. dichloromethane or dichloroethane, ethers, e.g. tetrahydrofuran or 1,4-dioxane or carboxamides, e.g. N,N-dimethylformamide, N,N-dimethylacetamide or N-methylpyrrolidone. Step i) is ordinarily carried out at temperatures in the range from −20° C. to +25° C.

Subsequently, in a second step ii), the hydroxy diamide compound IV is oxidized to the carboxamide compound I of the invention. Various conventional oxidation reactions are suitable for this (see R. C. Larock, Comprehensive Organic Transformations, VCH Publisher, 1989, page 604 et seq.) such as, for example, swern oxidation and swern analogous oxidations (T. T. Tidwell, Synthesis 1990, pp. 857-870) or Pfitzner-Moffatt oxidation. Suitable oxidizing agents are dimethyl sulfoxide (DMSO) in combination with dicyclohexylcarbodiimide or 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide, dimethyl sulfoxide in combination with the pyridine-SO₃ complex or dimethyl sulfoxide in combination with oxalyl chloride, sodium hypochloride/TEMPO (S. L. Harbenson et al., J. Med. Chem. 1994, 37, 2918-2929) or hypervalent iodine compounds such as the Dess-Martin reagent (J. Org. Chem. 1983, 48, 4155) or IBX (J. Org. Chem. 1995, 60, 7272). Depending on the oxidizing agent used, the oxidation of the hydroxy amide compound IV takes place at temperatures of from −50 to +25° C.

Alternatively the compounds of the formula I can also be prepared according to the synthetic route depicted in scheme 2.

In scheme 2, R¹, R², R³, R⁴, R⁵, m and n exhibit the aforementioned meanings and the variable PG is a protective group.

In a first step i), a carboxylic acid II is converted by reaction with an amino hydroxy ester V into a corresponding hydroxy amido ester VI using a procedure discussed above for the analogous step i) of scheme 1. The protective group PG of compound VI may be any protective group known in the art to be suitable for blocking carboxylic acid groups and is preferably selected from C₁-C₆-alkyls, in particular methyl and ethyl. In subsequent step ii) the protective group PG is removed using costumary methods. In case PG is an alkyl group the reaction is preferably carried out by treating compound VI with a base in an aqueous medium, for example lithium hydroxide in a tetrahydrofuran (THF)/water mixture. In the following step iii) the resulting carboxylic acid is coupled with the amine VII to the hydroxy diamide IV employing a peptide coupling method as described above for step i) of scheme 1. The compound IV is then converted to the target compound I according to step ii) of the preceding process depicted in scheme 1.

The amino hydroxy amides III can be obtained by purchase or can be prepared by processes disclosed in the literature (see, for example, S. L. Harbenson et al., J. Med. Chem. 1994, 37, 2918-2929 or J. P. Burkhardt et al., Tetrahedron Lett. 1988, 29, 3433-3436) or in analogy to the processes described in the preparation examples.

The 3-(S)-diastereomers III′ of the propanamide derivatives III which are deuterated in the 3-position, can be synthesized starting form alkinol VIII in analogy to a 9-step process described by F. Maltais et al., J. Med. Chem. 2009, 52 (24), 7993-8001 (DOI 10.1021/jm901023f), as shown below. According to this process chiral resolution of the intermediately obtained racemic mixture is achieved via amidation with deoxycholic acid. By employing compounds III′ in the synthesis of scheme 1 compounds I-D which are S-configurated at the carbon atom carrying the radical R¹ are accessable.

The amines VII and the amino hydroxy esters V are either commercially available or can be prepared according to established processes. The derivatives of compounds V that in place of hydrogen carry a deuterium at the carbon atom bound to R¹, are accessable using an apparent variant of the aforementioned process by F. Maltais et al.

The carboxylic acid II can be prepared by hydrolyzing the carboxylic ester IX with acids or bases under generally customary conditions. The hydrolysis preferably takes place with bases such as alkali metal or alkaline earth metal hydroxides, for example lithium hydroxide, sodium hydroxide or potassium hydroxide in aqueous medium, such as a mixture of water and organic solvents, e.g. alcohols such as methanol or ethanol, ethers such as tetrahydrofuran or dioxane, at room temperature or elevated temperature such as 25-100° C.

In formulae II and IX, R², R⁴, R⁵, m and n have the aforementioned meanings. In formula IX, R⁷ is alkyl, preferably C₁-C₆-alkyl.

The carboxylic ester of the formula IX can advantageously be obtained by reacting the carboxylic ester of the general formula X with a pyrazole compound XI, see scheme 3.

In scheme 3, LG represents a nucleophilically displaceable leaving group. Examples of suitable nucleophilically displaceable leaving groups are halogen, e.g. chlorine or bromine, or tosylate. R⁷ is alkyl, preferably C₁-C₆-alkyl. R², R⁴, R⁵, m and n have the aforementioned meanings.

As shown in scheme 3, an ester X is reacted with an appropriate pyrazole compound of the formula XI. The reaction is ordinarily carried out under conventional conditions in the presence of a base in an inert solvent at elevated temperature. It may be advantageous where appropriate to carry out the reaction in the presence of catalytically active amounts of a transition metal, in particular of a metal of group 10 or 11 in the periodic table.

The reaction is preferably carried out at elevated temperature without diluent or in an inert solvent such as an ether, e.g. tetrahydrofuran or dioxane, carboxamides such as N,N-dimethylformamide, N,N-dimethylacetamide or N-methylpyrrolidone, or an aromatic hydrocarbon such as benzene, toluene or o-, m- or p-xylene. The reaction takes place in the presence of inorganic or organic bases and of a crown ether. Suitable inorganic bases are alkali metal or alkaline earth metal amides such as sodium amide, alkali metal or alkaline earth metal carbonates such as potassium carbonate or cesium carbonate or alkali metal hydrides such as sodium hydride. Suitable organic bases are tertiary amines, such as, for example, trimethylamine or triethylamine. A suitable crown ether is 18-crown-6. A Cu(I) salt such as, for example, CuI, CuCN, Cu₂O is added where appropriate as catalyst (see, for example, U.S. Pat. No. 4,826,835 and WO 88/00468).

The pyrazole compounds XI can be purchased or can be prepared by conventional methods, which are briefly outlined below, from precursors which can be obtained by purchase.

General methods for preparing pyrazoles of the general formula XI are described for example in R. Fusco in “The Chemistry of Heterocyclic Compounds: Pyrazoles, Pyrazolines, Pyrazolidines, Indazoles and Condensed Rings”, Wiley, R. H., editor; Wiley: New York, 1967; Vol. 22, pages 1-174; or J. Elguero, in “Comprehensive Heterocyclic Chemistry”; Potts, K. T., Ed.; Pergamon: Oxford 1984; Vol. 5, pages 291-298. One of the most commonly used methods is cyclocondensation of 1,3-dicarbonyl compounds or correspondingly reactive analogs with hydrazine or substituted hydrazine derivatives.

3-Aryl- or 3-hetaryl-substituted pyrazoles XI are particularly advantageously prepared by reacting 1-aryl- or 1-hetaryl-3-dimethylamino-2-propene compounds with hydrazine in analogy to the processes described for example in M. A. Halcrow et al.; J. Chem. Soc. Dalton Trans. 1997, pages 4025-4035. The 1-aryl- or 1-hetaryl-3-dimethylamino-2-propenes required as starting material can easily be prepared by condensing the analogous aromatic acetyl compounds with N,N-dimethylformamide dimethyl acetal (or analogously using the corresponding diethyl acetal). The reaction is normally carried out without diluent or in an inert solvent such as, for example, dimethylformamide or toluene, at elevated temperature. It is particularly advantageous to introduce the activation energy necessary for the reaction into the reaction mixture also by means of microwaves and to carry out the reaction under elevated pressure as described in A. K. Pleier, Synthesis 2001, 1, 55-62.

A further general possibility for preparing substituted pyrazoles of the formula XI is the Suzuki coupling of appropriate pyrazoleboronic acids or pyrazoleboronic esters as described for example in: N. Zhe et al.; J. Med. Chem. 2005, 48 (5), 1569-1609; Young et al.; J. Med. Chem. 2004, 47 (6), 1547-1552; C. Slee et al.; Bioorg. Med. Chem. Lett. 2001, 9, 3243-3253. An appropriate alternative is also Stille coupling of halogenated pyrazole derivatives with appropriate tin organyls as described for example by J. Eluguero et al.; Synthesis 1997, 5, 563-566.

The reaction mixtures are worked up in a conventional way, e.g. by mixing with water, separating the phases and, where appropriate, purifying the crude products by chromatography. The intermediates and final products in some cases result in the form of colorless or pale brownish, viscous oils which are freed of volatiles or purified under reduced pressure and at moderately elevated temperature. If the intermediates and final products are obtained as solids, the purification can also take place by recrystallization or digestion.

If individual compounds I are not obtainable by the routes described above, they can be prepared by derivatization of other compounds I.

The compounds of the invention exhibit extremely low Ki values in relation to the inhibition of calpain and thus permit efficient inhibition of calpain, especially calpain I, at low serum levels. The compounds of the invention ordinarily exhibit Ki values in relation to the inhibition of calpain in vitro of <1500 nM, preferably <800 nM, in particular <400 nM and specifically ≦250 nM. The compounds of the invention are therefore particularly suitable for the treatment of disorders associated with an elevated calpain activity.

In addition, the compounds of the invention are selective calpain inhibitors, i.e. the inhibition of other cysteine proteases such as cathepsin B, cathepsin K, cathepsin L or cathepsin S takes place only at concentrations which are distinctly higher than the concentrations necessary for inhibition of calpain. Accordingly, the compounds of the invention ought to show distinctly fewer side effects than the prior art compounds which are comparatively unselective in relation to inhibition of calpain and likewise inhibit other cysteine proteases.

Compounds preferred according to the invention accordingly have a selectivity in relation to inhibition of cathepsin B, expressed in the form of the ratio of the Ki for inhibition of cathepsin B to the Ki for inhibition of calpain of ≧5, in particular ≧9 and specifically ≧30.

Compounds preferred according to the invention accordingly have a selectivity in relation to inhibition of cathepsin K, expressed in the form of the ratio of the Ki for inhibition of cathepsin K to the Ki for inhibition of calpain of ≧5, in particular ≧9 and specifically ≧30.

Compounds preferred according to the invention accordingly have a selectivity in relation to inhibition of cathepsin L, expressed in the form of the ratio of the Ki for inhibition of cathepsin L to the Ki for inhibition of calpain of ≧5, in particular ≧10 and specifically ≧50.

Compounds preferred according to the invention accordingly have a selectivity in relation to inhibition of cathepsin S, expressed in the form of the ratio of the Ki for inhibition of cathepsin S to the Ki for inhibition of calpain of ≧5, in particular ≧10 and specifically ≧50.

In addition, the compounds of the present invention feature an improved stability in the cytosole of human cells, which markedly contributes to their good overall metabolic stability. The cytosolic stability can be measured for example by incubating a solution of a compound of the invention with liver cytosole from particular species (for example rat, dog, monkey or human) and determining the half-life of the compound under these conditions. It is possible to conclude from larger half-lives that the metabolic stability of the compound is improved. The stability in the presence of human liver cytosole is of particular interest because it makes it possible to predict the metabolic degradation of the compound in the human liver. Compounds with enhanced cytosolic stability therefore are likely to be degraded at reduced rates in the liver. Slower metabolic degradation in the liver in turn can lead to higher and/or longer-lasting concentrations (effective levels) of the compound in the body, so that the elimination half-life of the compounds of the invention is increased. Increased and/or longer-lasting effective levels may lead to a better efficacy of the compound in the treatment or prophylaxis of various calpain-dependent diseases. An improved metabolic stability may additionally lead to an increased bioavailability after oral administration, because the compound is subjected, after being absorbed in the intestine, to less metabolic degradation in the liver (termed the first pass effect). An increased oral bioavailability may, because the concentration (effective level) of the compound is increased, lead to a better efficacy of the compound after oral administration.

Accordingly, due to their improved cytosolic stability the compounds of the invention remain in the cytosol for extended periods, i.e. have a decreased cytosolic clearance, and therefore ought to show enhanced human pharmacokinetics.

Compounds preferred according to the invention accordingly have a cytosolic clearance in human liver cytosol of ≦30 μl/min/mg, in particular of ≦15 μl/min/mg.

The improved cytosolic stability of the compounds according to the present invention is probably primarily due to their reduced susceptibility to aldo-keto reductases (AKRs) which mediate the metabolic degradation of compounds having a carbonyl group in the liver cytosole of humans and monkeys. Thus, the AKR-catalyzed reduction of the ketoamides of formula I should be less pronounced than that of less stable ketoamides. Hence, the ratio of the concentration of the parent compound, i.e. the ketamide of formula I, to the concentration of the metabolite, i.e. the hydroxyamide stemming form the ketoamide, is a measure for the stability of the compounds of the invention.

Compounds preferred according to the invention accordingly have, after an incubation in human hepatocytes for 4 hours, a concentration ratio of the hydroxyamide metabolite to their corresponding parent compound of formula I of ≦5, in particular ≦2 and specifically ≦0.5.

Owing to their inhibitory effect on calpain, their selectivity for calpain in comparison with other cysteine proteases and their cytosolic stability the compounds of the present invention, including their tautomers, their hydrates and their pharmaceutically suitable salts are particularly suitable for the treatment of a disorder or of a condition which is associated with an elevated calpain activity as are described for example in the prior art cited at the outset.

Disorders associated with an elevated calpain activity are in particular neurodegenerative disorders, especially those neurodegenerative disorders occuring as a result of a chronic brain supply deficit, of an ischemia (stroke) or of a trauma such as brain trauma, and the neurodegenerative disorders Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis and Huntington's disease, also multiple sclerosis and the damage to the nervous system associated therewith, especially damage to the optic nerve (optic neuritis) and the nerves which control the movement of the eye. Accordingly, preferred embodiments of the invention relate to the treatment of neurodegenerative disorders, especially of the aforementioned neurodegenerative disorders in humans, and to the use of the compounds of the invention of the formula I, their tautomers and their pharmaceutically suitable salts for the manufacture of a medicament for the treatment of these disorders.

Disorders associated with an elevated calpain activity also include epilepsy. Accordingly, preferred embodiments of the invention relate to the treatment of epilepsy in humans, and to the use of the compounds of the invention for the manufacture of a medicament for the treatment of epilepsy.

The disorders or conditions associated with an elevated calpain activity also include pain and painful conditions. Accordingly, preferred embodiments of the invention relate to the treatment of pain and painful conditions in mammals, especially in humans, and to the use of the compounds of the invention for the manufacture of a medicament for the treatment of pain and painful conditions.

The disorders or conditions associated with an elevated calpain activity also include damage to the heart following cardiac ischemias, damage to the kidneys following renal ischemias, skeletal muscle damage, muscular dystrophies, damage arising through proliferation of smooth muscle cells, coronary vasospasms, cerebral vasospasms, macular degeneration, cataracts of the eyes, or restenosis of blood vessels following angioplasty. Accordingly, preferred embodiments of the invention relate to the treatment of diseases or conditions associated with damage to the heart following cardiac ischemias, damage to the kidneys following renal ischemias, skeletal muscle damage, muscular dystrophies, damage arising through proliferation of smooth muscle cells, coronary vasospasms, cerebral vasospasms, macular degeneration, cataracts of the eyes, or restenosis of blood vessels following angioplasty in mammals, especially in humans, and to the use of the compounds of the invention for the manufacture of a medicament for the treatment of these disorders.

It has further emerged that inhibition of calpain brings about cytotoxic effects on tumor cells. Accordingly, the compounds of the invention are suitable for the chemotherapy of tumors and metastasis thereof. Preferred embodiments of the invention therefore relate to the use of the compounds of the invention in the therapy of tumors and metastases, and to their use for the manufacture of a medicament for the therapy of tumors and metastases.

It has further been found that various impairments associated with an HIV disorder, especially nerve damage (HIV-induced neurotoxicity), are mediated by calpain and therefore inhibition of calpain allows such impairments to be treated or alleviated. Accordingly, the compounds of the invention are suitable for the treatment of HIV patients. Preferred embodiments of the invention therefore relate to the use of the compounds of the invention for the treatment of HIV-infected patients, especially the treatment of those impairments caused by an HIV-induced neurotoxicity, and to their use for the manufacture of a medicament for the treatment of HIV patients.

It has further been found that the release of interleukin-I, TNF or beta-amyloid peptides (Aβ or Aβ-peptides) can be reduced or completely inhibited by calpain inhibitors. Accordingly, impairments or disorders associated with an elevated interleukin-I, TNF or Aβ level can be treated by using the compounds of the invention of the formula I, their tautomers and their pharmaceutically suitable salts. Preferred embodiments of the invention therefore relate to the use of the compounds of the invention for the treatment of impairments or disorders associated with an elevated interleukin-I, TNF or Aβ level such as rheumatism, rheumatoid arthritis and to their use for the manufacture of a medicament for the treatment of such impairments or disorders.

It has further emerged that inhibition of calpain is suitable for the treatment of protozoan infection (protist infection) like malaria or toxoplasmosis (Li et al., Mol Biochem Parasitol. 2007; 155(1): 26-32; Jung et al. Archives of Pharmacal Research (2009), 32(6), 899-906). Hence, the compounds of the present invention are particularly suitable for treating protozoan infections like malaria or toxoplasmosis and to their use for the manufacture of a medicament for the treatment of such impairments or disorders.

Besides their improved cytosolic stability the compounds of the present invention are also distinguished by a good stability against degradation in liver microsomes. The microsomal stability of a compound can be measured for example by incubating a solution of this compound with liver microsomes from particular species (for example rat, dog or human) and determining the half-life of the compound under these conditions (R S Obach, Curr Opin Drug Discov Devel. 2001, 4, 36-44). Their good microsomal stability contributes to the enhanced overall metabolic stability of the compounds of the invention.

The compounds of the present invention are further distinguished by exhibiting an improved pharmacological activity, compared with the carboxamide compounds disclosed in the prior art, in patients or relevant animal models allowing prognostic statements for use in treatment.

The present invention also relates to pharmaceutical compositions (i.e. medicaments) which comprise at least one compound of the present invention and, where appropriate, one or more suitable drug carriers.

Thes drug carriers are chosen according to the pharmaceutical form and the desired mode of administration.

The compounds of the presemt invention can be used to manufacture pharmaceutical compositions for oral, sublingual, subcutaneous, intramuscular, intravenous, topical, intratracheal, intranasal, transdermal or rectal administration, and be administered to animals or humans in unit dose forms, mixed with conventional pharmaceutical carriers, for the prophylaxis or treatment of the above impairments or diseases.

Suitable unit dose forms include forms for oral administration, such as tablets, gelatin capsules, powders, granules and solutions or suspensions for oral intake, forms for sublingual, buccal, intratracheal or intranasal administration, aerosols, implants, forms of subcutaneous, intramuscular or intravenous administration and forms of rectal administration.

The compounds of the invention can be used in creams, ointments or lotions for topical administration.

In order to achieve the desired prophylactic or therapeutic effect, the dose of the active basic ingredient may vary between 0.01 and 50 mg per kg of body weight and per day.

Each unit dose may comprise from 0.05 to 5000 mg, preferably 1 to 1000 mg, of the active ingredient in combination with a pharmaceutical carrier. This unit dose can be administered 1 to 5 times a day, so that a daily dose of from 0.5 to 25000 mg, preferably 1 to 5000 mg, is administered.

II Spectrin Molt-4 Assay to Determine Cellular Calpain Inhibition:

The following solutions and buffers were employed:

-   HBS (for 40 ml): 800 μl 1M HEPES; 2.16 ml 100 mM KCl; 4.8 ml 1M     NaCl; 3.59 ml 5% glucose; 60 μl 1M MgSO₄; 400 μl 100 mM Na pyruvate,     28.19 ml water; pH 7.2-7.5. -   lysis buffer (for 20 ml): 400 μl 1M Tris pH 8.2; 2.74 ml 1M NaCl;     520 μl 0.5M EDTA; 2 ml 10% triton X-100; 0.8 ml (=1:25) CompletePlus     (1 tablet/2 ml H₂O); 200 μl 100 mM Pefabloc; 13.34 ml water, pH 8.2. -   TBST (10×) (for 1l): 100 mM Tris (12.1 g); 1.5M NaCl (87 g); 1%     Tween 20 (10 g), adjusted to pH 8.

The assay design and procedure were as disclosed by Chatterjee; BMC 1998, 6, pp. 509-522; the EC₅₀ values are calculated from the percentage degradation of spectrin as a function of the dose.

Cell culture conditions: the molt-4 cells are maintained in RPMI 1640+Glutamax™ I medium (Gibco) with 10% FCS and 50 μg/ml gentamicin at 37° C., 5% CO₂ and split 1:15 twice a week.

Preparation of the molt-4 cells: the cells are washed, counted and taken up in a concentration of 2×10⁷ cells/ml in HBS buffer.

Dilution of the inhibitor substances: all the inhibitors are dissolved in a concentration of 10⁻² M in DMSO. The stock solution is then diluted 1:15 in DMSO (=6.67×10⁻⁴ M). Thereafter the stock solution diluted 1:15 is diluted 1:4 in DMSO in two steps (=1.67×10⁻⁴ M and 4.17×10⁻⁵ M). Thereafter, these three solutions are further diluted 1:50 in HBS buffer to give solutions having a concentration of 1.33×10⁻⁵ M, 3.36×10⁻⁶ M and 8.34×10⁻⁷ M.

Test mixture: for each mixture, 10⁶ cells (see above) are introduced into a 1.5 ml Eppendorf tube. To these are added in each case 150 μl of the diluted substances (final conc. 10-5 M; 2.5×10⁻⁶ M and 6.25×10⁻⁷ M) and thoroughly mixed. A negative control and a positive control are used as controls. In this case, initially only 150 μl of HBS buffer is pipetted onto the cells. All the mixtures are incubated at 37° C., 5% CO₂ in an incubator for 10 mM Thereafter, except for the negative control, in each case CaCl₂ (final conc. 5 mM) and ionomycin (final conc. 5 μM) are added, thoroughly mixed and incubated at 37° C., 5% CO₂ in an incubator for 30 mM Then centrifuge at 700 g for 5 mM The supernatants are discarded and the pellets are taken up in 20 μl of lysis buffer. The mixtures are subsequently placed on ice for 30-60 mM and then centrifuged at 15000 g for 15 min. The supernatants are removed and put into new Eppendorf tubes. The protein determination is then carried out thereon, e.g. with a MicroBCA assay (Pierce).

SDS-PAGE electrophoresis: 10 μg of total protein from each mixture are put into a new Eppendorf tube and, after pipetting in the same volume of 2× Tris-glycine SDS sample buffer (Invitrogen) and 1/10 volume of 1M DTT, thoroughly mixed and heated at 95° C. for 15 mM The solutions are briefly centrifuged and loaded onto a 6% SDS gel (Invitrogen). The gel is run at 100V with 1× Tris-glycine laemmli buffer (Biomol) until the lower band of the marker has reached the base of the gel.

Western blotting: the gel is removed from the apparatus and blotted onto nitrocellulose in 1× Tris-glycine transfer buffer (Invitrogen)+20% methanol with 1.5 A/cm² in a FastBlot chamber (Biometra) for 30 mM The nitrocellulose filter is removed, briefly washed in TBST buffer and blocked in TBST/5% milk powder for 1 h at RT (room temperature). The blocked nitrocellulose is then incubated with an anti-spectrin Ab (Chemicon) (1:10000 in TBST/5% milk powder) at RT for 3 h or at 4° C. overnight. The nitrocellulose is washed 3× in TBST buffer. It is then incubated with anti-mouse IgG (POD) antibody (Sigma) (1:10000 in TBST/5% milk powder) at room temperature for 1 h.

The nitrocellulose is then washed 5× in TBST buffer. In the next step, 5 ml of prepared solution of the SuperSignal® West Pico chemiluminescence substrate (Pierce) are put on the filter and incubated for 5 mM The nitrocellulose is then taken out of the solution, gently dabbed dry and inserted into a development folder film (Tropix). A digital image analysis system (VersaDoc, Biorad) is used to record and quantify the ECL (QuantityOne), and the percentage degradation of spectrin is calculated from the data. Graph-pad prism is used to fit the percentage spectrum degradation as a function of the dose to a sigmoidal dose-effect plot (top fixed at 100% and bottom at 0%), and the EC 50% is calculated.

III Assay for Determining Cytosolic Clearance of Compounds of Formula I:

For comparision purposes data measured with human liver cytosol were contrasted with those obtained with cynomolgus monkey liver cytosol.

0.5 μM of a compound to be tested was incubated with 1 mg/ml of human liver cytosol as well as monkey liver cytosol at 37° C. in 0.5 M of phosphate buffer at pH 7.5 while shaking (commercial sources: female cynomolgus liver cytosol from Tebu bio, human liver cytosol from BDgentest).

In each case aliquots of 65 μl were taken after 0, 5, 10 and 15 min and transferred into wells of a wellplate which were immediately filled with 130 μl of ethanol to stop the reaction. The samples were kept frozen until analysis on a LC/MS/MS system (Applied Biosystems SCIEX 4000).

Read out parameters were the loss of parent compounds, from which the half life periods (T_(1/2)) were calculated from. Based on these data the parameters cytosolic clearance (cytCL), scaled clearance (CLs) and predicted clearance (CLp) were calculated using the following equations: cytCL=(ln 2/T _(1/2))×[cytosolic protein]×1000  1) CLs=cytCL×[cytosolic yield]/1,000,000×60  2) CLp=(CLs+hepatic plasma flow)/hepatic plasma flow/CLs  3)

To assess the stability of the compounds tested the clearance ranges were adjusted to the hepatic plasma flow of the different species according to the following scheme:

stable=from 0 to about ⅓ of the hepatic plasma flow;

moderately stable=from about ⅓ to about ⅔ of the hepatic plasma flow;

instable=more than ⅔ of the hepatic plasma flow.

Based on this adjustment the following qualifiers were assigned to evaluate the cytosolic stabilities of the compounds tested:

cynomolgus cytCL symbol human monkey (cyno) stable ++ 0-14 μl/min/mg 0-18 μl/min/mg moderately stable + 14-70 μl/min/mg 18-90 μl/min/mg instable − >70 μl/min/mg >90 μl/min/mg

The cytCL data obtained this way for the compounds of the Examples 1 to 18 are depicted in Table 1 above. As can be seen from Table 1 the compounds of formula I according to the invention feature improved stabilties over the related compound of WO 08/080969 having an unsubstituted carboxamide moiety (comparative Example 18).

IV In-Vitro Assay for Determining Degradation of Compounds I into the Corresponding Hydroxyamide Metabolites in Hepatocytes:

Each compound to be tested (10 μl) was incubated in monkey and also in human hepatocytes to determine the concentration ratio of hydroxyamide metabolite to the compound of formula I as parent compound. Incubations were carried out at 37° C. for 0 and 4 hours in a 24-well plate, each well holding 0.5 ml hepatocyte medium with about 500,000 cells/ml. At the end of each time point, 1 ml of acetonitrile/ethanol (1/1, v/v) was added to each well to quench the reaction. The solutions were vortexed and mixed thoroughly. An aliquot was subjected to LC-UV-MS/MS analysis at UV wavelength of 254 nm Identities of compounds I tested and their corresponding hydroxyamide metabolites were confirmed by MS/MS analysis and by comparison with synthetic standards. UV areas for each test compound and its hydroxylamide metabolite were integrated. The concentration ratios of hydroxyamide metabolites to parent compounds (M/P ratios) were determined as ratios of the UV areas of metabolites to those of the compounds I, assuming that extinction coefficients ε_(P) and ε_(M) are approximately identical. The M/P ratios obtained this way for incubations terminated after 4 hours are shown in Table 2.

TABLE 2 M/P ratio Example cyno human 5 0.03 0.2 18 (comp.) 3.4 8

As can be seen from Table 2 the reductive degradation of the compound of Example 5 according to the invention is much slower in both human and cyno hepatocytes as compared to the related compound of WO 08/080969 (comparative Example 18).

V In-Vivo Determination of the Ratio of Hydroxyamide Metabolite to the Parent Compound I in Plasma of Cynomolgus Monkeys

The tested compounds were prepared as a solution for either intravenous or oral administration to groups of female cynomolgus monkeys. For intravenous dosing, the compounds were prepared in a 10% DMSO/PEG-400 vehicle at a concentration of 2 mg/ml. For oral dosing, the compounds were prepared in a lipid based vehicle at a concentration of 3 mg/ml. Groups of three monkeys received either a 1 mg/kg (0.5 ml/kg) intravenous dose or a 3 mg/kg (1 ml/kg) oral dose. The intravenous dose was administered as a slow bolus in a saphenous vein; the oral dose was administered by gastric intubation and was followed by ˜5 ml water. Serial blood samples were obtained from each animal at selected time points up to 24 hours after drug administration. Plasma was separated from the blood by centrifugation and stored frozen (<−15 C.) until analysis. Parent compounds I and the selected metabolites were separated from plasma using protein precipitation with mixture of methanol, acetonitrile and water. The supernatant was evaporated to dryness with a stream of dry nitrogen. The samples were reconstituted with an aliquot of mobile phase, followed by quantification by HPLC-MS/MS. Standard curves for both parent and the selected metabolites were prepared from authentic standards in blank monkey plasma; standards were analyzed simultaneously with the samples. The plasma concentration of each sample was calculated by least squares linear regression analysis of the peak area ratio (parent or metabolite/internal standard) of the spiked plasma standards versus concentration.

Peak plasma concentrations (C_(max)) and the time to peak plasma concentration (T_(max)) were read directly from the plasma concentration data for each monkey. The plasma concentration data for both parent and metabolite were submitted to multi-exponential curve fitting using WinNonlin. The area under the plasma concentration-time curve from 0 to t hours (time of the last measurable plasma concentration) after dosing (AUC_(0-t)) was calculated using the linear trapezoidal rule for the plasma concentration-time profiles. The residual area extrapolated to infinity, determined as the final measured plasma concentration (Ct) divided by the terminal elimination rate constant (β), was added to AUC_(0-t) to produce the total area under the curve (AUC_(0-inf)). The apparent total plasma clearance (CL_(p)) was calculated by dividing the administered dose by the AUC_(0-inf). The initial volume of distribution (V_(c)) was calculated as the dose divided by the extrapolated concentration at time=0 (C₀). The volume of distribution at steady state, V_(ss), was estimated as a product of the plasma clearance (CL_(p)) and the mean residence time (MRT); the terminal-phase volume of distribution (V_(β)), was derived from the plasma clearance value (CL_(p)) divided by the plasma elimination rate constant (β). The bioavailability was calculated as the dose-normalized AUC_(0-inf) from the oral dose divided by the corresponding value derived from the intravenous dose. Metabolite to parent ratios were calculated as the C_(max) (metabolite)/C_(max) (parent) or AUC(metabolite)/AUC(parent) for the peak concentrations and area under the curve, respectively. Results obtained in these ways are shown in Table 3.
